It only left Vallkyrie more confused and as he left the tree to move on, so did she, dull nails slicing at the bark in her wake. She began to think that the youth might be pulling her chain but the embarrassed expression on his features told her otherwise. 

Dodging to the next tree, the boy quickly dismissed it and moved on once more, tree to tree, looking as Vallkyrie did, her white neck out stretching. Frustrated it seemed without the ability to explain himself, he asked her name instead. Vallkyrie. She easily answered, And yours? She then asked as long and lean legs once more lifted up onto the side of a tree, peering within its branches. 

Small. Brown. Big eyes. In the trees... Your friend isnt a squirrel, is she?
